摘要：

Here we report a new sensor Tb97.11Eu2.89-L1 that enables ratiometric detection of trace water in CH3CN. As the water content increases from 0% to 2.5% ( v/ v%), Tb97.11Eu2.89-L1 exhibits an excellent linear relationship between the water content and I-543/ I-615, as well as variable emissive light colors visible to the naked eye.
